Title: Pre-coupling spring bow for model railways - is made as additional fitting for attachment to short couplings and used in conjunction with uncoupling rail
Inventor: GATZEMEIER HANS H
IPC: A63H19/18
Filed: 1979-06-18
Abstract: The pre-coupling spring bow for model railway couplings is an additional fitting to be attached to the short coupling and tbe pin provided on tbe coupling would normally push the spring bow back during shunting of the carriages because the pin runs against tbe bow with the coupling locking in tbe normal way. When the coupling is opened by using the uncoupling rail, the coupling hook with the pin is moved so far outwards that the spring bow is released and moves into its exit position. The coupling hook can no longer be locked so that the coupling remains open and any wagons to be uncoupled can be pushed further as required.

Title: Control system for valve - prevents hunting by using actual pressure and rate of change of pressure as control parameters
Inventor: SANDER MICHAEL DIPL ING DR ING
IPC: G05D16/20
Filed: 1980-11-14
Abstract: The control system uses both the magnitude of the pressure and the rate of pressure to control the opening and closing of the valve. This prevents the valve being operated unnecessarily, when the pressure fluctuates, and for eliminating overshoot when the valve is operated. If the valve is designed to open at 165 bar and if the limit above which the valve is controlled by the rate of pressure change is 160 bar, the valve is opened at 161 bar in the presence of pressure gradients above 1 bar/s., but not until 165 bar with pressure gradients less than 1 bar/s has been reached.

Title: DC motor speed stabilising circuit - uses control transistors to apply compensating voltage to armature winding when current falls
Inventor: BAUER ANTON
IPC: H02P7/288
Filed: 1980-12-18
Abstract: The circuit for stabilising the speed of a d.c. motor, applies a compensating voltage to the armature winding when the armature winding current falls due to a fall in voltage. The armature current combined with the motor voltage is used as a control criterion. The control circuit includes a resistance (5) in series with the armature winding and a transistor (2) acting as a variable resistance to apply the compensating voltage. This transistor is controlled by an amplifier using two further transistors (3,4) forming inverting and non inverting inputs. The voltage corresponding to the armature current is applied to the non inverting input and the voltage of the armature winding is applied to the inverting input. The first transistor (2) has its main electrode connected to the armature winding, its second main electrode connected to a d.c. supply and its control electrode connected to the transistor (3) forming the driver transistor.

Title: Automatic device for switching on hazard warning lights
Inventor: HANSEN ADOLF PAUL ERNST
IPC: B60Q1/52
Filed: 1981-02-25
Abstract: The automatic device for switching on hazard warning lights in a travelling vehicle is actuated by the deceleration of the vehicle in the event of a rear-end collison or by full manual braking in that the carrier bracket (12, in Figure 1 and Figure 2) is pressed against the switching plunger (29, in Figure 1 and Figure 2) and the said plunger actuates the switch (10, in Figure 1 and Figure 2). The circuit is then closed and the magnets (4 and 5, in Figure 1 and Figure 2) lock the carrier bracket (4) and the hazard light is switched on. For manual switching on, the magnets (4, 5, in Figure 1 and Figure 2) are given a separate current feedline (2, in Figure 1 and Figure 2). This is switched on by the lever switch (33, in Figure 1 and Figure 2). The magnetic field of the magnet (4 and 5) impinges on the carrier bracket (12) and locks the same. <IMAGE>

Title: Furnace installation for combustion of solid fuels
Inventor: PAUL EDGAR
IPC: F23L1/02
Filed: 1981-06-26
Abstract: A furnace installation for combustion of solid fuels, such as e.g. pieces of wood, wood chips, turf, straw or the like, has above an ash grate (10) a shelf surface (5) which is approximately as wide as the incoming-air opening (6) of the furnace installation. This shelf surface (5) begins shortly behind the incoming-air opening (6) and extends as far as the rear wall of the furnace installation. The air flowing in is divided by a control flap (8) into a primary air-flow above the shelf surface (5) and a secondary air-flow below the shelf surface (5). This gives rise to a two-stage combustion. Furthermore, the fire is prevented from going out on refilling the furnace installation because a material deflection plate (4) is arranged above the incoming-air opening (6). <IMAGE>

Title: Method for producing and applying combined games played with striking implements and special low-bounce balls
Inventor: REPPERT RUEDIGER LOTHAR VON
IPC: A63B37/02
Filed: 1981-09-01
Abstract: For combined games to be played with striking implements and special low-bounce balls, use is to be made not only of commercially available striking implements but also of lightweight balls made from foamed plastics or sponge rubber which, because of cores which are fitted within them and are made to be heavier than the enclosing outer layer, can still be well controlled in their flight and yet are so light that even the hardest shots can do no damage to sensitive parts. The size of the core fitted in the inside of the ball is, in this arrangement, to be up to a maximum of approximately half the diameter of the ball and its weight is to be one-fifth to three times, preferably one-half to one and a half times, heavier than a foam ball of identical size without core. The new sport of "light-ball" tennis thus played is played with lightweight tennis balls which measure 60 to 90 mm in diameter and weight about 40 g. For the identical "light-ball golf", by contrast, light-weight golf balls are used with a diameter of only 40 to 60 mm and a weight of about 40 g. Both new types of sport can be played anywhere, both in the open air and in enclosed spaces, with the commercial rackets/clubs available for tennis and golf.
